## Summary description

The BlueOptics 25GB-4-C05-QSFP28 is a 5 m InfiniBand fibre optic cable featuring a QSFP28 connector on one end and 4xSFP28 connectors on the other. It is designed for high-speed data transmission in data centers and networking applications, ensuring reliable performance and minimal signal loss.

## Long description

The BlueOptics 25GB-4-C05-QSFP28 InfiniBand fibre optic cable 5 m 4xSFP28 is a high-speed breakout cable designed for data center interconnects and high-performance computing environments. With a QSFP28 connector at one end and four SFP28 connectors at the other, this 5-metre multimode fibre assembly enables aggregation and distribution of four 25 Gbps lanes from a single QSFP28 port to four independent SFP28 ports, enabling flexible cabling for switches, servers and storage equipment while limiting signal loss over short to medium distances.
Advantages
This BlueOptics cable provides a compact, factory-terminated solution that reduces the need for separate transceivers and simplifies rack cabling. The breakout design offers predictable lane mapping and stable optical performance across all four channels. Constructed for data center use, the cable delivers low insertion loss and consistent transmission characteristics to support InfiniBand networking and other 25 Gbps applications.
Suitable for
Connecting QSFP28 ports to multiple SFP28 ports for server and switch interconnects
High-performance computing clusters and InfiniBand fabrics
Top-of-rack and end-of-row cabling in data centers
Short- to medium-reach 25 Gbps links where compact breakout cabling is required
Key specifications
Cable type: Multimode fibre breakout cable
Connector configuration: 1 × QSFP28 to 4 × SFP28
Length: 5 metres
Supported lane speed: 25 Gbps per SFP28 channel
Application: InfiniBand and 25 Gbps Ethernet-compatible interconnects
Typical characteristics: Low insertion loss, factory-terminated connectors
How to use
Identify the QSFP28 port on the source device and align the QSFP28 connector carefully before inserting to avoid damaging the transceiver ports. Route the cable to the target device(s) and connect the four SFP28 connectors to the corresponding SFP28 ports on switches, servers or NICs, ensuring correct lane mapping if required by your equipment. Secure cable runs to avoid excessive bending radii and mechanical strain; verify link status in your network equipment management interface after installation to confirm proper operation.
Usage recommendations
Maintain recommended bend radius for multimode fibre, avoid tight bends and kinks, and keep connector end faces clean using appropriate fibre cleaning tools. Use this cable for short- to medium-reach connections within racks and between adjacent racks; confirm compatibility with device port specifications and lane mapping requirements before deployment.
